Question: An electromagnetic wave in a vacuum has a magnetic field with a magnitude of {eq}1.7 \times 10^{-6}\ T {/eq}. What is the intensity S of the wave? The intensity of EM Wave The intensity of an electromagnetic wave i...
When such oscillations travel (that is, when the swinging does not stay bound to one place) then we speak of waves propagating in space. For example, a singer singing creates periodic oscillations in his or her vocal cords. These oscillations periodically compress and decompress the air, and t...
Waves can travel either forward or backward (e.g.reflections) along a transmission line. We distinguish between the two by using the + and the – subscript. Hence B V is the complex amplitude of the forward voltage wave. 1.2. Travelling Wave Equations The Teleg...
Electromagnetic waves are waveforms that perpendicularly intersect the electric and magnetic fields and are essentially generated by the flow of electric current. In order to control the interference provided by electromagnetic waves, various electromagnetic shielding technologies have been recently studied. El...
When these waves travel through conductive material, the electromagnetic energy is lost in the form of heat through the electric current. This loss of energy is the attenuation that provokes a reduction in the depth of the penetration of the radar waves....
